How to make a node have simulated values

Question:

If I create a Node in atvise, is it possible to make it have simulated data without being connected to any data source.

Answer:

Yes, for this you will need to create a script in the Node itself.

This script will be time trigered.

The script  is written as follows:

//se puede usar como trigger un timer

//el script se coloca dentro del tag que queremos simular

// Let value hover around 50 in-between 0 and 100;

var nodeId = base.nodeid;

var valueNode = new UaNode(nodeId);

var currentValue = valueNode.value;

// Generate a new value for the change size (1 - 5)

var changeValue = Math.random() * (5 - 1) + 1;

// The more the value diverges from 50, the more it gets pulled

// back toward 50.

// How: We draw a number from a pool of number between 0 and 100.

// Since we revolve around 50, the smaller our current value is,

// the higher the change we pull a greater number, and thus increase

// the currentValue (and vice verse).

var numberFromPool = Math.random() * 100;

if (numberFromPool <= currentValue) {

    valueNode.value = currentValue - changeValue;

} else {

    valueNode.value = currentValue + changeValue;

}
